FIELD OF TECHNOLOGY

The present invention generally relates to Internet of Things (IoT), and more particularly relates to an IoT-based system for predictive and preventive maintenance of machines that uses a blower and a pump, through machine learning and physics based modeling of physical parameters like vibration, sound, temperature monitored by machine wearable and other related sensors.

BACKGROUND

Internet of Things (IoT) is a network of uniquely-identifiable and purposed “things” that are enabled to communicate data over a communications network without requiring human-to-human or human-to-computer interaction. The “thing” in the Internet of Things may virtually be anything that fits into a common purpose thereof. For example, a “thing” could be a person with a heart rate monitor implant, a farm animal with a biochip transponder, an automobile comprising built-in sensors configured to alert its driver when the tire pressure is low, or the like, or any other natural or man-made entity that can be assigned with a unique IP address and provided with the ability to transfer data over a network. Notably, if all the entities in an IoT are machines, then the IoT is referred to as a Machine to Machine (M2M) IoT or simply, as M2M IoT.

It is apparent from the aforementioned examples that an entity becomes a “thing” of an M2M IoT especially, when the entity is attached with one or more sensors capable of capturing one or more types of data pertaining to: segregation of the data (if applicable); selective communication of each segregation of data to one or more fellow “things”; reception of one or more control commands (or instructions) from one or more fellow “things” wherein, the control commands are based on the data received by the one or more fellow “things”; and execution of the commands resulting in manipulation or “management” of an operation of the corresponding entity. Therefore, in an IoT-enabled system, the “things” basically manage themselves without any human intervention, thus drastically improving the efficiency thereof.

EP Patent No. 1836576 B1 discusses a diagnostic method of failure protection of vacuum pumps. Based on comparison of the currently evaluated diagnostics analysis results and an initial data, maintenance engineers would decide the replacement of the considered vacuum pump, according to the evaluated pump performance indicators. However, in this prior art invention, there is no mention of machine learning or use of machine wearable sensors. Also, the remedial decisions are left to the maintenance engineers.

US Patent application 20120209569 A1 discusses a method for predicting a failure in rotation of a rotor of a vacuum pump. The prior art invention fails to disclose machine learning capabilities and also is dependent on an observation time prediction window. Further, the prior art fails to disclose machine wearable sensors and Internet of things.

U.S. Pat. No. 7,882,394 B2 discusses fault diagnostics through a data collection module. The prior art discloses a system for condition monitoring and fault diagnosis that includes: a data collection function that acquires time histories of selected variables for one or more of components; a pre-processing function that calculates specified characteristics of time histories; an analysis function for evaluating the characteristics to produce one or more hypotheses of a condition of the components, and a reasoning function for determining the condition of the components from one or more hypotheses. The prior art invention however, fails to suggest the concept of IoT. Further, the prior art invention does not mention machine learning for effective predictive or preventive maintenance of vacuum pumps or similar devices.

It is evident from the discussion of the aforementioned prior art that none of them discloses or suggests regarding predictive and preventive maintenance of vacuum pumps through machine learning. Therefore, there is a need in the art for a solution to the aforementioned problem.

SUMMARY

A method of machine learning architecture according to the present invention includes a step of: receiving data from machine wearable sensors placed on a motor (henceforth motor sensor data) and a blower (henceforth a blower sensor data) over a communications network. The machine wearable sensors can be selected from a group consisting of vibration sensors, temperature sensors, magnetic field sensors, gyroscope and its combinations thereof. The sensor type can be single silicon or MEMS (Micro-electromechanical systems) type. The motor or blower sensor data is classified into one of a vacuum state sensor data and vacuum break state (where rotor is switched off and the revolution of the rotor is gradually damping in vacuum medium) sensor data, wherein the vacuum state sensor data is further analyzed to detect an operating vacuum level and an alarm is raised when the vacuum state sensor data exceeds a pre-defined safety range. The vacuum break state sensor data is then classified into clean filter category and clogged filter category and an alarm is raised if the real time data of sensors belonging to clogged filter category is detected. Vacuum state data is further classified based on a multi-class learning model which classifies a pump running with machine oil into clean, old, leaked or overfilled classes. If the sensor data suggest neither, it is classified under uncategorized bearing issues. The blower sensor data in association with the motor sensor data is analyzed based on machine learning to detect deficient oil level and deficient oil structure.

The mobile application is communicatively coupled to one or more machine wearable sensors, over the communications network. The mobile application can be replaced by a PC based communication such as a PC based app, as well. The machine learning architecture receives sensor data from the blower and the motor and classifies the motor sensor data into vacuum state sensor data and break state sensor data. Also, the machine learning architecture analyzes the vacuum state sensor data to detect an operating vacuum level and an alarm is_raised when the vacuum state sensor data exceeds a pre-defined safety range. The machine learning architecture classifies vacuum break data into clean filter category and clogged filter category and an alarm is raised if an entry under the clogged filter category is detected, and the machine learning architecture further analyzes the blower sensor data in association with the motor sensor data through a machine learning algorithm in order to detect at least one of a deficient oil level and a deficient oil structure.

The present invention relates to an Internet of Things (IoT) based system for overseeing process control and predictive maintenance of a machine or a network of machines by employing machine wearable sensors. The IoT based system includes a plurality of machine-wearable sensors, secured to the exterior of the machine. These sensors can be any combination of Temperature sensors, Vibration sensors, Magnetometer, Gyroscope. Each sensor is capable of transmitting captured data wirelessly over a communications network.
